Abstract

The invention discloses a curved-surface electrode plasma generating device for solving uneven discharge, and a working method, and relates to the field of plasma generation. The curved-surface electrode plasma generating device comprises a gas inlet pipeline, rectifying plates, a gas outlet pipeline, a shell and a discharge treatment unit, wherein gas enters the shell through the gas inlet pipeline, is treated by the discharge treatment unit and then is discharged through the gas outlet pipeline, the rectifying plates are arranged at the joint of the gas inlet pipeline and the shell and the joint of the shell and the gas outlet pipeline, and the discharge treatment unit is arranged in the shell and is used for generating plasmas. Aiming at the problems that the traditional plasma generating device discharges unevenly after being amplified and partial discharge is easily caused, the invention designs the efficient and stable plasma generating device which solves the problem of uneven discharge, and the device can be applied to the fields of organic waste gas treatment and the like.

Description

technical field [0001] The invention relates to a plasma generating device, in particular to a curved surface electrode plasma generating device and a working method for solving uneven discharge. Background technique [0002] Plasma is currently a common method for treating organic waste gas, and has the advantages of a wide range of applicable reactants and simple equipment. Plasma generators are generally composed of high-voltage electrodes, grounding, and high-voltage power supplies. In laboratories, flat electrodes or needle electrodes are often used. However, in practical applications, this structure often causes uneven discharge during operation. This leads to a sudden drop in the treatment efficiency of organic waste gas and a sharp increase in energy consumption. In addition, the uneven discharge will also affect the service life of the device. Solving the problem of uneven discharge is of great significance to the large-scale application of plasma technology in wa...
